4.1 The student will plan and conduct investigations in which
a) distinctions are made among observations, conclusions, inferences, and predictions;
b) hypotheses are formulated based on cause-and-effect relationships;
c) variables that must be held constant in an experimental situation are defined;
d) appropriate instruments are selected to measure linear distance, volume, mass, and temperature;
e) appropriate metric measures are used to collect, record, and report data;
f) data are displayed using bar and basic line graphs;
g) numerical data that are contradictory or unusual in experimental results are recognized; and
h) predictions are made based on data from picture graphs, bar graphs, and basic line graphs.

Activities


4.2 The student will investigate and understand characteristics and interaction of moving objects. Key
concepts include
a) motion is described by an object's directions and speed;
b) forces cause changes in motion;
c) friction is a force that opposes motion; and
d) moving objects have kinetic energy.

Activities


4.3 The student will investigate and understand the characteristics of electricity. Key concepts include
a) conductors and insulators;
b) basic circuits (open/closed, parallel/series);
c) static electricity;
d) the ability of electrical energy to be transformed into heat, light, and mechanical energy;
e) simple electromagnets and magnetism; and
f) historical contributions in understanding electricity.

Activities


4.4 The student will investigate and understand basic plant anatomy and life processes. Key concepts
include
a) the structures of typical plants (leaves, stems, roots, and flowers);
b) processes and structures involved with reproduction (pollination, stamen, pistil, sepal, embryo, spore,
and seed);
c) photosynthesis (sunlight, chlorophyll, water, carbon dioxide, oxygen, and sugar); and
d) dormancy.

Activities

1. Students can create a Plants tree map using Inspiration.


4.5 The student will investigate and understand how plants and animals in an ecosystem interact with one
another and the nonliving environment. Key concepts include
a) behavioral and structural adaptations;
b) organization of communities;
c) flow of energy through food webs;
d) habitats and niches;
e) life cycles; and
f) influence of human activity on ecosystems.

4.6 The student will investigate and understand how weather conditions and phenomena occur and can be
predicted. Key concepts include
a) weather measurements and meteorological tools (air pressure - barometer, wind speed - anemometer,
rainfall - rain gauge, and temperature - thermometer); and
b) weather phenomena (fronts, clouds, and storms).

Activities

1. Students can create a Cloud slideshow using Microsoft PowerPoint.

2. Have students complete a
Weather Observation Chart and answer questions about weather using Microsoft
Excel. They can also make a graph of the week's temperature.


4.7 The student will investigate and understand the relationships among the Earth, moon, and sun. Key
concepts include
a) the motions of the Earth, moon, and sun (revolution and rotation);
b) the causes for the Earth's seasons and phases of the moon;
c) the relative size, position, age and makeup of the Earth, moon, and sun; and
d) historical contributions in understanding the Earth-moon-sun system.

Activities


4.8 The student will investigate and understand important Virginia natural resources. Key concepts include
a) watershed and water resources;
b) animals and plants;
c) minerals, rocks, ores, and energy sources; and
d) forests, soil, and land.
